DRILL.

SPECIFICATION forming part of Letters Patent No. 772,003, dated October 11, 1904.

Application filed December 14, 1903. Serial No. 185,084. (No model.)

To add whom, it may concern:

Be it known that I, WILLIAM H. SoLEY, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Drills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object to provide a construction of drill whereby the tool may be rotated or moved by the operator instead of by power, as is the case in the present construction.

I will first describe my invention as embodied in the accompanying drawings and then specifically point out the invention in the claims.

In the drawings, Figure 1 is a view, partially in section, of my improved drill. Fig.

2 is a section on line 2 2, Fig. 1. Fig. 3 is a plan view of the lower end of the drill.

A represents the casing forming the cylinder of the tool, in which is piston-chamber B 5 and the valve-chamber C. At the lower end of the casing A a bushing D is inserted rectangular in interior cross-section and in which the tool is adapted to be placed, so as to. be rotatably held thereby.

E is the handle, which rests above a projection a from the casing A. The handle is secured to the casing by means of the sleeve F, which has the projection f resting beneath the projection a from the casing A. This 3 5 sleeve F is threaded and meshes with a thread on the exterior of the handle E.

G is a boss projecting from the sleeve F, on which boss is loosely mounted the gearwheel H. r

I is a handle secured to the gear-wheel H by screws 2' for rotating the same. The gear H meshes with the gear-wheel J, said wheel having a threaded portion which meshes with a threaded portion a, formedon the casing A.

Through the handle E is formed a passage K for connection with the air-supply. At the point where this passage K passes into the valve-chamber O a washer L is interposed between the handle and the casing A. This washer is formed of flexible material and has a cut-away portion Z, which under action of compressed air when said compressed air is admitted to the valve-chamber will expand and open, as shown in Fig. 1, thus making an air-tight joint between the handle and the cas- 1ng.

As may be seen from the above construction, the casingA is rotatably mounted upon the handle E, so that when the gear H is revolved it will, through the medium of gear J, revolve the casing, and when the tool is placed in the bushing D it will be revolved with the casing. In the piston-chamber B is the piston b, and in the valve-chamber a suitable valve (not shown) is placed. The piston and valve and the ports and passages connecting the valve-chamber and the piston-chamber may be of any well-known construction-such, for instance, as that shown in my application, Serial No. 173,653, filed September 18, 1903 and need not be further described or illustrated, as neither the construction of the valve nor the piston nor the ports and passages connecting the valve-chamber and piston-chamber form any part of my invention.

I do not intend to limit myself to the specific construction illustrated and described in the specification except as the same may be specifically claimed.

Having now fully described -my invention, what I claim, and desire to protect by Letters Patent, is

1. In a drill, the combination with the cylinder of the drill to which the tool is ad aptcd to be connected so as to revolve therewith, of a support upon which said cylinder is revolubly mounted, and means to revolve said cylinder.

2. A drill, comprisingin combination, a casing, a handle, said casing being adapted to revolve on the handle and means to revolve said casing.

3. In a drill, the combination with the cylinder of the drill to which the tool is adapted to be connected so as to revolve therewith, of a support upon which said cylinder is revolubly mounted.

4c. Adrill comprising, in combination, acasing, a gear secured thereto, a handle, said casing being adapted to revolve on said'handle, a gear revolubly secured to said handle meshing with the casing-gear.

5. In a drill, the combination with the cyl inder of the drill, of a gear secured thereto, a support on which said cylinder is revolubly mounted, and a gear revolubly secured to said support meshing with the cylinder-gear.

6. A drill comprising, in combination, a casing, a gear secured thereto, a handle, a sleeve securing said handle and easing so that said casing is revolubly mounted, a gear revolubly secured to said handle meshing with the easing-gear.

7. In a drill of the character described, in combination, a casing, a handle, said handle and easing being secured together so that said casing is revoluble, there being an orifice in said handle, and a flexible washer having expanding portions interposed between the easing and the handle at the oriliced portion.

8. In a drill of the character described, in combination, a casing, a support, said support and easing being secured together so that said casing is revoluble, there being an orifice in said support, and a flexible washer having expanding portions interposed between the easing and the support at the orificed portion.

9. In a drill, the combination with the cylinder of the drill, of a gear secured thereto, a support, a sleeve securing said support and cylinder, so that said cylinder is revoluble on the support, a projection from said sleeve, a gear loosely mounted on said projection, a gear on the cylinder with which said last-mentioned gear meshes.

10. In a drill, in combination, a casing, a gear secured thereto, a handle, a sleeve securing said handle and easing so that said casing is revoluble on the handle, a projection from,

said sleeve, a gear loosely mounted on said projection, a gear in the casing with which said last-mentioned gear meshes.

In testimony of which invention 1 have hereunto set my hand, at Philadelphia, on this 4th day of December, 1903.

WILLIAM H. SOLEY.
